Impinj Inc (NASDAQ: PI) is a semiconductor and systems company that designs and sells RAIN RFID technology, including endpoint ICs, reader ICs, readers, gateways, and tag production systems used to wirelessly identify and track physical items. Revenue comes primarily from selling silicon endpoint ICs embedded into RAIN tags by inlay partners, plus reader systems, software, and cloud services sold through partners and distributors. Impinj describes itself as the only company with an integrated platform spanning endpoint ICs, reader ICs, and readers, a claim supported by its Gen2X air-interface extensions that go beyond the base RAIN standard. Key end markets include retail apparel and general merchandise, supply chain and logistics, automotive manufacturing, and healthcare. The company sells most products through partners and distributors rather than directly to enterprises. Impinj is headquartered in Seattle and its Voyantic Oy subsidiary sells tag production systems primarily to inlay partners. As of the 10-K filed February 9, 2026, the company carried $190.0 million in convertible notes due 2029, issued in September 2025, bearing no regular interest.

Revenue model

Transactional product sales of endpoint ICs (silicon chips embedded in RAIN tags), reader ICs, finished readers, gateways, and tag production systems sold through partners and distributors. Software is sold bundled with readers or standalone. Cloud services for item resolution and label authentication are offered separately, described as nascent from a standalone revenue perspective as of the FY2025 10-K filing.

Products and services

Endpoint ICs (serialized, optionally cryptographic silicon chips for item identification), reader ICs (used by partners in embedded or finished readers), finished readers and gateways, tag production systems (sold through Voyantic Oy subsidiary), software for package sortation and retail loss prevention, and cloud services for item resolution and label authentication. The platform includes proprietary Gen2X extensions to the RAIN air-interface standard.

Customers and end markets

Retailers (apparel, footwear, general merchandise including home goods, health and beauty, tires, toys, consumer electronics), supply chain and logistics operators (conveyor sortation, returnable transit item tracking, asset management), automotive manufacturers (parts tracking for vehicle assembly), and healthcare. Products reach enterprises primarily through inlay partners and distributors.

Value-chain role

Fabless semiconductor designer and systems vendor sitting upstream of inlay manufacturers and systems integrators. Impinj designs endpoint ICs and reader ICs, which partners embed into tags and readers respectively, then deploy to enterprise end users. Voyantic Oy sells tag production systems to inlay partners.
